Is there anywhere that this is broken down by program, it is not obvious from looking at the wikipedia simple pie graph that this is the case.

>Capitalism requires an unregulated free market based economy.
It is not clear what you mean here. Adam Smith seems to have been a proponent for the government paying for some public goods and regulation
> It was the role of the government to provide goods "of such a nature that the profit could never repay the expense to any individual"
> provide public goods such as infrastructure, provide national defense and regulate banking.

Which agrees with what I have read and been told elsewhere through the years.
